Error type for IP packet parsing.

Variants

Parse

Fields

error: ParseError

ParameterProblem

For errors where an ICMP Parameter Problem error needs to be sent to the source of a packet.

Fields

src_ip: I::Addr

The packet’s source IP address.

dst_ip: I::Addr

The packet’s destination IP address.

code: I::ParameterProblemCode

The ICMPv4 or ICMPv6 parameter problem code that provides more granular information about the parameter problem encountered.

pointer: I::ParameterProblemPointer

The offset of the erroneous value within the IP packet.

must_send_icmp: bool

Whether an IP node MUST send an ICMP response if action specifies it.

See action for more details.

header_len: I::HeaderLen

The length of the header up to the point of the parameter problem error.

action: IpParseErrorAction

The action IP nodes should take upon encountering this error.

If must_send_icmp is true, IP nodes MUST send an ICMP response if action specifies it. Otherwise, the node MAY choose to discard the packet and do nothing further.

If the packet was an IPv4 non-initial fragment, action will be IpParseErrorAction::DiscardPacket.

Trait Implementations

impl<I: Debug + IcmpIpExt> Debug for IpParseError<I>

where I::Addr: Debug, I::ParameterProblemCode: Debug, I::ParameterProblemPointer: Debug, I::HeaderLen: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<I: IcmpIpExt> Display for IpParseError<I>

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<I: IcmpIpExt> Error for IpParseError<I>

where Self: Debug + Display,

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl<I: IcmpIpExt> From<OptionParseErr> for IpParseError<I>

fn from(error: OptionParseErr) -> Self

Converts to this type from the input type.

impl<I: IcmpIpExt> From<ParseError> for IpParseError<I>

fn from(source: ParseError) -> Self

Converts to this type from the input type.

impl<I: PartialEq + IcmpIpExt> PartialEq for IpParseError<I>

where I::Addr: PartialEq, I::ParameterProblemCode: PartialEq, I::ParameterProblemPointer: PartialEq, I::HeaderLen: PartialEq,

fn eq(&self, other: &IpParseError<I>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
